I bought a SPAL universal window kit on EBAY. This is the kind that mounts to the existing winder. The motor & shaft fits OK, however the nylon adapter unit which slides over the window winder shaft would not fit tightly enuf to crank the window. Perhaps if it was epoxied into place ?. I opted to leave manual for now. Perhaps the kits that support the bottom of the glass would be better, although there are some internal brace issues. No suggestions for locks
